IPC: G10L19/00
Filed: 2002-04-19
Abstract: <P>PROBLEM TO BE SOLVED: To prevent deterioration of sound quality due to a concealment processing to be performed when packet loss occurs in the packet voice communication of VoIP, etc.  <P>SOLUTION: A decoding circuit 30 decodes a voice from a packet which reaches an input terminal 15, stores in an updating buffer circuit 38 an internal signal which is generated by the decoding and used for decoding the succeeding packet, generates a concealing voice based on the internal signal stored in the updating buffer circuit 38 with respect to a non-arrival packet, and outputs it. In this case, an updating circuit 40 recognizes that the concealing voice generated by the decoding circuit 30 is not largely deviated from an original voice, and, then, updates the internal signal of the updating buffer circuit 38 through the use of the concealing voice. Thus, the degree of noncoincidence in the internal signals generated by a concealment processing in an encoder and a decoder is reduced, so that deterioration in sound quality is reduced in decoding the packet after the concealment processing.  <P>COPYRIGHT: (C)2004,JPO
